Overview
The ADV3219ACPZ-RL, produced by Analog Devices Inc., is a high-speed, high slew rate, buffered, 2:1 analog multiplexer. This component is part of the ADV3219 and ADV3220 series, which are designed for high-speed signal switching applications. The ADV3219 has a gain of +1, while the ADV3220 has a gain of +2. Both devices operate on ±5 V supplies and consume less than 7.5 mA of idle current. They are available in an 8-lead LFCSP package and support an extended industrial temperature range of −40°C to +85°C.
